Construcción de una antena reconfigurable tipo planar sobre una estructura de torre pentagonal basada en técnicas de origami
(2019-05)
In this thesis shows the process of design and construction of an antenna based on origami techniques, which uses a pentagonal tower structure that works similar to a spring, made in Kraft paper, which allows changes in ...
Análisis matemático del conformado en el proceso de embutición cilíndrica de una sola fase, para evaluar el comportamiento mecánico de una chapa bimetálica
(2018)
In this project is done a mathematical analysis, to evaluate the behavior of a bimetallic sheet in a single-phase cylindrical drawing process, eliminating wrinkles in the flange. The results are validated by simulation in ...
Desarrollo de un microinversor para la optimización del arranque en motores monofásicos
(2019-01)
The present work starts with the study of the operation of the single-phase motors, their traditional starting techniques and the evolution of the electrical variables of voltage and current. The investigation continues ...
